Bad, stale gas makes a car run crappy, and I would agree with what you say normally, but the car is running great other than the fast idle. If its too lean would that make it idle fast?

yup did you create a extra air leak. Blew a vacuum hose off or blew the carb gasket or... power valve diaphram. A air leak will make it idle faster for sure.
I'd be getting it corrected before running that blower motor again under boost.
Cannot endorse using low octane fuel.
